5 Claims.

This invention relates to improvements in stationery, and has for its object to provide a strip of paper with transverse perforations or score lines therein dividing the strip into sheets, and

5 arranging the sheets in superimposed relation-' ship, with a sheet of carbon between each two adjacent strips of paper.

It is also an object of this invention to provide a sheet of carbon having at each end a perforation or hole, and strengthening means on each side of the carbon sheet around the hole.

It is also an object of this invention to provide, in connection with a plurality of superimposed strips of paper divided by cross markings into sheets, a plurality of interleaved carbon sheets, with cooperating means on all of the sheets whereby the carbon sheets may be removed from one set of paper sheets to the other by swinging the carbon sheets around a fixed point in the strips of paper.

It is a further object of this invention to provide a method by which one or more sheets of carbon may be successively interleaved between successive sets of sheets of paper formed in superimposed strips of paper by successively swinging the carbon sheets from one set of sheets of paper to an adjacent set of sheets of paper.

These and other objects will appear from the following description taken in connection with the drawing. I

Referring to the drawing:

Figure 1 is a plan view of one end of a strip of paper, divided by suitable cross markings into sheets, each sheet having at its forward end a hole.

Figure 2 is a top plan view of a sheet of carbon.

Figure 3 is a section on the line 3--3 of Figure 1.

Figure 4 is a section on the line 4-4 of Figure 2.

Figure 5 is a perspective view showing the relation between the paper sheets and the carbon/ sheets when they are assembled one upon the other.

Figure 6 is a top plan view of a plurality of superimposed strips of paper with carbon sheets between the strips of paper.

Figure '7 is a view similar to Figure 6 but showing the carbon sheets partly removed from the superimposed strips.

Figure 8 shows the carbon sheets removed from one set of paper sheets to an adjacent set of paper sheets.

Figure 9 is a view similar to Figure 8 but showing the paper sheets from which the carbon sheets have been removed entirely severed, but not withdrawn.

Figure 10 shows a key that may be used for swinging the carbon sheets from one set of paper sheets to an adjacent set of paper sheets.

Figure 1 shows one end of a strip lof paper divided by cross perforations or score lines 2 into sheets 3, which may be severed from one another along the lines 2. In the front or forward end of each sheet of paper, in the center thereof, is a hole or perforation 4, about which the carbon sheets may be pivoted for removing the carbon sheets from one set of paper sheets to an adjacent set of paper sheets.

Figure 3 shows a carbon sheet 5, which has in each end, at the center thereof a hole or perforation 6. Around each hole, and on each side of the carbon sheet, is some strengthening means 7. In the present. instance the strengthening means consists of discs of fiber, or some suitable material, located around the hole or perforation on each side of the sheet of carbon. This hole may be round, may be square, or any other convenient shape, but is shown square.

In Figure 6, which shows a carbon sheet beneath a strip of paper, a pencil or other pointed object may be inserted through the holes 4 and 6, at the rear of the advanced sheet. With this pointed instrument inserted in these holes the carbon sheet or sheets may be seized by the thumb and a finger of one hand and swung from between the end paper sheets and caused to be interleaved between the sheets of paper forming the secondset of sheets of paper.

In Figure 7 the carbon sheet or sheets is shown in one position in the operation of removing the sheets of carbon from the advanced paper sheets to the sheets of paper of the second set. In Figure 8 the carbon sheets have been removed entirely from the advanced paper sheets and are between the paper sheets forming the second set. When the sheets are in the position shown in Figure 8 the sheets of paper 3 may be torn along the lines 2, as shown in Figure 9. In the event that the holes or perforations 6 are square or angular in shape a key, such as that shown in Figure 10, may be used. This key consists of a wing-like member 8 and a projection with a square or angular portion 9 adapted to fit in one of the holes 6. The holes or perforations 4 in the sheets of paper are round so that the key may be readily turned in these holes.

When the advanced sheets of paper have been written upon and it is desired to remove the carbon sheets therefrom to an adjacent set of paper sheets, the key is inserted into the holes 4 with the square part 9 fitting in the correspondingly shaped holes 6, at the rear ends of the carbon sheets. The key is then turned so that the carbon sheets are rotated with the key as a pivot, from between the advanced paper sheets to the paper sheets immediately to the rear thereof, as shown in Figure 8.

It will be noticed that the holes 4 are in the advanced end of each sheet of paper so that when the carbon sheets are rotated about an object in these holes what were the rear ends of the carbon sheets at the end of rotation become the front ends of the carbon sheets, and will be in line with the front edges of the sheets of paper. However, the carbon sheets when they are properly aligned with the strips of paper extend partly over the front ends of the adjacent sheets of paper so that the holes in the rear ends of the carbon sheets are in alignment with the holes 4 in the front end of the second set of paper sheets.

The holes 4 and 6 are so arranged that when the paper sheets and the carbon sheets are properly aligned these holes are in alignment, and

when the carbon sheets are shifted from one set.

of paper sheets to an adjacent one, the holes are again in alignment. The front holes of the carbon sheets are in alignment with the holes in the front ends of the first set of paper sheets, while the holes in the rear ends of the carbon sheets are in alignment with the holes in the front ends of the second set of paper sheets.

These relationships continue throughout the whole operation of the various sheets of paper. After one set of sheets of paper has been used and torn off an adjacent set of sheets of paper, with carbon sheets interleaved therebetween, is ready for use. This operation continues until all of thesheets of paper have been used.

It will be understood that it is desired to comprehend within this invention such modifications as come within the scope of the claims and the invention.

Having thus fully described the invention, what is claimed as new and desired to be secured by Letters Patent, is:

1. An article of stationery consisting of superimposed strips of paper, said strips being divided into similar superimposed sheets by cross perforations, the forward end of each sheet having a hole therein, and a carbon sheet between the superimposed sheets, said carbon sheet being slightly longer than the superimposed sheets, the carbon sheet having at each end at the center thereof a hole, said carbon sheet holes being adapted to align with the holes in the adjacent sheets of paper.

' 2. An article of stationery consisting of superimposed strips of paper, said strips being divided into similar sections of superimposed sheets by cross perforations, and a carbon sheet between the superimposed sheets of one section, said carbon sheet being slightly longer than the superimposed sheets, the-carbon sheet having at each end at the center thereof a hole and each sheet of paperhaving at its forward end a hole for alignment with one of the holes in the carbon sheet.

3. An article of stationery consisting of superimposed strips of paper divided into equal attached sheets, each sheet having at one end at the center thereof a hole, and a carbon sheet having at each end a hole, each hole of the carbon sheet adapted to align with holes in the paper sheets when the carbon sheet is interleaved between superimposed sheets.

4. In combination, superimposed strips of paper divided into equal attached sheets each sheet having at one end at the center thereof a hole, a carbon sheet between superimposed sheets and extending beyond the holes therein and beyond the holes in adjacent superimposed sheets, and means extending through the last-named holes to engage the carbon sheets to swing the carbon sheets from between one set of sheets of paper to and betweenthe sheets having the last-named holes.

5. In combination, a plurality of superimposed strips of paper having spaced round holes therein, carbon sheets interleaved between the strips of paper, each of said carbon sheets having in each end a square hole in linewith holes in the strips of paper, and a key adapted to be inserted in the holes, said key having a square part to engage the square holes in the carbon sheets, whereby on rotation of the key the carbon sheets will be swung from one' part of the strips of paper to another part.
